Definitions

  • the Internet Protocol IP at level 3 of the OSI layered model is responsible for the connectionless transport of data from a sender—possibly over a plurality of networks—to the recipient, providing neither error detection nor error correction.
  • Transport protocols such as the Transmission Control Protocol TCP or User Datagram Protocol UDP are situated above the Internet Protocol, and then above these comes an almost limitless multiplicity of different and sometimes competing application protocols such as http and FTP, for example, or (for the management of multimedia connections) the so-called SIP protocol or the ITU standard H.323.
  • the means whereby known services can be implemented are defined in parallel and alternatively by the ITU-T standard Q.1902.XBICC CS2 (bearer independent call control capability set 2) and Q.765.5 BAT (bearer application transport).
  • the invention resolves a conflict which is produced by contradictory requirements of two subscribers on a connection. For example, this case occurs if e.g. the calling subscriber activates the performance feature “CALL Transfer” and the called subscriber activates a feature from the “CALL Forwarding” group. In these cases, for reasons of network loading, it is desirable for the basic channel of the connection to be routed via a direct path between the newly included subscribers.
  • the figure shows a call being established between a calling subscriber SIP, which has an ISDN connection interface in the exemplary embodiment and wishes to establish a call connection to a further subscriber SIP.
  • the ISDN device of the caller RT uses ISDN User Part (ISUP) signaling.
  • ISUP ISDN User Part
  • IWP interworking unit
  • so-called outband signaling takes place, i.e. basic channel and signaling are routed via separate paths.
  • the ITU-T standard Q.1902.X BICC CS2 (bearer independent call control capability set 2) and Q.765.5 BAT (bearer application transport) define how known services can be implemented.
  • BICC APM1 with UPDATE offer 1 action indicator “bearer redirect” as per Q.765.5/1902.6
  • the method according to the invention can also be applied in an identical or obviously similar manner to any case in which contradictory requirements in the protocol interworking result in a need for resolution when establishing or controlling a connection in packet-switched networks.
  • the invention is also not restricted to individual signaling protocols, interworking configurations or individual services in this case.
